The present invention relates to textile pile I fabrics and method for making same, and particularly to carpets and rugs having decorative designs formed in relief on the face of the fabric.

An object of this invention is to provide an improved and novel method for making pile fabrics of the character mentioned, whereby a three tone effect is obtained in a carpet, using but a single color yarn as pile material.

Another object hereof is to provide a novel and improved three tone carpet having pile areas of different character though all pile material is the same and of one color.

A further object of the present invention is to provide a novel and improved carpet construc- 22 Claims. (Cl. 139-391) stance on the high wires, The density of the pile yarn and the closeness of weave, causes the low tion and method for making same, which requires no change in' present carpet making machinery, is economical, practical and effective in producing the desired result as described.

Other objects and advantages will become ap-- parent as this disclosure pr eeds.

In the accompanying d awings forming part of this specification, similar characters of reference indicate corresponding parts in all the views.

Fig. 1 shows pictorially, the pile surface of a pile loops thus formed to overlap the empty rows. 'I'he'pile areas marked B" are obtained by having double strands of pile yarn raised by the loom on the high wires; no pile being raised in this instance on the low wires. When said high wires are withdrawn, as known in the art, such high loops are cut to form tuft which splays; thus covering the intermediate rows in which no pile had been raised. The pile areas marked "C" are obtained by having double strands of pile yarn raised b the loom on the low wires, and single strands on the high wires. Upon withdrawal of the wires, the high loops are cut. In such areas C, the out high loops which are now termed tufts, willcause a shadow to fall on the relatively dense uncut low loops.

In the drawings, the numeral I5 designates the low uncut loops, the numeral l6 designates the carpet made in accordance with the teachings of this invention, presenting a three tone effect.

Fig. 2 is. a diagrammatic view showing in elevation, the pile structure for'surface areas of said carpet, which present one of the color tones.

Fig. 3 is a similar view of pile structure for surfaces, areas of said carpet, for presenting another color tone.

Fig. 4 is a similar view of the pile structure used for surfaces areas of said carpet, which present a third color tone.

In the manufacture of pile fabrics, the manner and equipment in use with the Jacquard loom for making rows of pile of high loops, low loops, cut to form tufts or left uncut. as well as the raising of double strands of pile yarn to form dense pile rows, and raising pile in only alternate rows, leaving the intermediate rows without pile being formed therealong, are all known. I will therefore proceed with a description of the character of the pile as used in the practice of this invention.

It is important to note, that for making the pile, a single kind of material of a single color is used for the entire pile surface of the carpet.

Two sets of wires are used on the loom for raising pile loops. One set having knives for cut ting the loops, are placedrelatively high and in alternate relation with the second set of wires which are relatively low. The low wires have no knives.

The pile areas marked "A are obtained by having double strands of pile yarn raised by the loom on the low wires; no pile being raised in this intuft of two strands each formed after the high pile loops are cut, and the numeral ll-designates the rows where no pile material is raised.

Adjacent rows as mentioned herein shall be deemed the consecutive rows as performed in weaving operations on the loom. I

The appearance of the respective pile areas will be different, and though the pile material used is the same for all areas and but of one color,

' the resulting entity will be a three tone carpet as can be observed in Fig. 1 which is a photographic showing of such carpet. r

This invention is capable of numerous forms and various applications without departingfrom the essential features herein disclosed. It is therefore intended and desired that the specific description herein be deemed illustrative and not restrictive and that the patent shall cover all patentable novelty herein set forth; referencebeing had to the following claims rather than to the particular showing herein to indicate the scope of this invention.

Iclaim:

A three tone pile fabric having on one of its surfaces, adjacent first, second and third tone areas; the first tone area comprising rows free of pile material and rows of uncut pile loops, in alternate relation; the loops of successive pile rows of the first tone area being in contact; the

second tone area comprising rows free of pile material and rows of tufts of few strands each. in alternate relation; the tufts of successive pile rows of the second tone area being in contact; the third tone area comprising rows of uncut pile loops and rows of tufts of few strands each, in alternate relation; all pile tufts being relatively high; all uncut pile loops being relatively low; all successive rows of the respective tone areas being 3 adjacent each other and all pile material being of a single color. i
